A common approach to programming bugs is to try and educate programmers to not make particular mistakes. A more effective approach is to redesign the language so those mistakes are impossible. Depends on what you want. Give me a powertool and I'll give a powerful result. Give me safety scissors and I'll take much longer, and the result will probably be inferior. And I can say with some certainty that both products will be roughly equal in terms of safety, because I pay careful attention to safety when designing and implementing systems. But the products will differ greatly in terms of feature set, extensibility, and robustness. It's difficult to add safety without subtracting power.
